My daughter is currently taking a gap year. It has done her a lot of good. She worked hard on her university applications, and obtained an unconditional offer of a place at her first choice university. She has travelled, read, partied, visited school friends already at university, cast her first votes, and obtained her first job, which she is enjoying (she's working in an upmarket wine shop and learning about wine). She might still get her driving test done before university. She has grown as a person. If you are not yet sure what you would like to do in the future, a gap year may help you to figure things out, and you will be able to select target universities based on your achieved grades. Good luck!
